Lube-Tech PUBLISHED BY LUBE: THE EUROPEAN LUBRICANTS INDUSTRY MAGAZINE Introduction


Everyone thinks they have a clear idea of what the term “wear part” means, but that does not necessarily mean that everyone’s understanding of the term “wear part” is the same as everyone else’s. There is good reason for this, as, perhaps surprisingly, there are still no standard definitions.

‘Wear’ and ‘wear parts’ in contextual relation with ‘obsolescence’


Dr. Mathias Woydt, MATRILUB, and Rolf Luther, Gesellschaft für Tribologie e.V., Aachen Summary of the position paper of the German Society for Tribology e.V.


The extension of service life, avoiding planned obsolescence, and, generally, the manufacture of more sustainable products contributes significantly to material efficiency, which translates into resource conservation and to energy efficiency. The concept of durability/service life is represented by the features of longevity, repairability and ease of maintenance of the product.
